I, for one, have no problem with a family holding a kid back (or reclassing him if that is the proper word) so that he can be in whatever grade they want the kid to be in. It just should be true that in youth lacrosse, these kids should play vs kids their same age. So if I have a 2005 kid, I want him to play against 2005 kids (or use a Sept 1-Aug 30 year). I don't care if his opponents are in 7th grade, 9th grade, 5th grade, or no grade at all. With regard to school lacrosse (Middle School Teams, JV, Varsity), there is a fair amount of consistency within leagues, conferences, ect. My kids are suburban NY public school kids. There are very few extreme hold backs in the public schools. The extreme holdbacks are mostly at the prep school, catholic schools, ect. The publics and the privates largely don't compete against each other except for non-league games that are voluntarily scheduled.
